Oh it wasn't last year, it was January this year. There's a patch at

This is because the _GLIBCXX_USE_WCHAR_T macro is not defined, because
 etc are not complete on the target, so we don't have e.g. wcslen and
other wchar_t functions.

However, the wchar_t type is always defined for C++ and so the template can be
used with it.

So not a bug, but the expected behaviour.

See mails from me last year about enabling more of the library without needing
, which would fix this.

However, std::basic_string_view works.
